Question

I have some data I need to display using MSChart, I am looking to plot data which is one of the following values taken at a particular datetime:

Low
Low-Medium
Medium
Medium-High
High

So I am looking for datetime along the X axis and the above values on Y

When I try and plot them something like this….

mySeries.Points.AddXY(dateA, "Low");
mySeries.Points.AddXY(dateB, "Low-Medium");
mySeries.Points.AddXY(dateC, "Medium");

The chart obviously doesn’t have any idea that Medium show be a larger bar than Low.

How can I specify this range of values for the Y Axis?

Answer 1

You can set numeric values as suggested in Kyle answer and then change the Y labels e.g.:

chart1.ChartAreas[0].AxisY.CustomLabels.Add(0, 1, "LOW"); 
// it means: on Y range = [0, 1] show the label "LOW" ...

chart1.ChartAreas[0].AxisY.CustomLabels.Add(2, 3, "MEDIUM");
chart1.ChartAreas[0].AxisY.CustomLabels.Add(3, 4, "HIGH");
